title: Registration errors in compound B-scans.
abstract: The effect of B-scanner articulated arm angle measurement errors on B-mode registration is considered. For a single-angle articulated arm model, a mathematical equation predicting B-mode misregistration as a function of angular errors and compound scan angle is derived and discussed. This model accurately predicts registration errors for transducer connector/acoustic axis misalignment or third arm angle errors.
